To all whom 'it may concern:

Be it known that I, ANDREAS \VALTHER Lnuscnnnn, a subject of the Emperor of Germany, residing at Dresden-Alt, Saxony, Germany, have invented certain new and useful Improvements in Production of Aerated Baths; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it apperlains to make and use the same.

This invention relates to certain new and useful improvements in the production of aerated or air bubble baths which have been "found of value for the treatment. of certain. nervous maladies and which are particularly invigorating for weakly and convalescent persons. 5 v

The essential noveltyof the invention con' sists in means for introducing the air into the bath with the iii-flowing stream of wa= ter,.and in intimate admixture and fine subdivision thcrein.

Prior to my invention, the production of air bubble baths has been effected by first filling the bath tub with Water alone and then injecting the air, that is, without preliminary admixture of the air with an incoming water current. This prior practice has the disadvantage that the air does not enter the water of the bath tub in line beadlikc sub-division nor intimately admixed with the Water, but issues from the exit openings of the air admission pipe in the form of larger air bubbles which do not enter into contact with the body of the bother in it directly effective and invigorat mg manner.

The purpose of the present invention is to overcome this dismlvanlage, and it consists in intimately admixing the air with the water on its way into the bath tub and in ln'ingin; it into an extremely fine state of sub-division in the latter. For this purpose, the air is drawn in by means of a water iet injector, is intimately admixed with the valor of the water jet, and then, together therewith, is introduced in the finest slate of subdivision into the bath tub which has already been lilled to the desired level nilh wate The introduction of the mixture of ail-4 l water into the bath tub takes place prelim; ably by means of an oval shaped pipe ring adapted to rest on the bottom of the bath tub, and having a seriesof perforations from which the mixtur of water and; air as issues into the bath eonnuuo' tcJ-J itself to the entire body ol Wat therein ii; a slate ht the finest sub-div so that an extremely intensive action 1 air bubbles 54 or bead-like air particles is exe ted upon the entire hot y of the bather. Simultane oiisly, the necessary amount of Warm water for tempering the mixture of cold water and air is admitted, -pr+ erahly helow the in jector and the cold in time of Water and air is immediately mixed with the warm water in such mannrr that, by reason of this further commingliug with the warm. Water, a still more intimate z nixture anti sub-division (it the air in the W takes place.

The perforated pipe ring; serving for the introduction of the mixture of water and air into the lJr-fh lul filled with Later which pipe ring lies upon lhe hottom bath tub is provided at the place where the mixture enters, as well at the opposite portion of the ring, with sarlelike extrusions, perforated at their free ends. These sack-like extensions are provided for the purpose of preventingr stagnation of the mixture of Water and air and have the lunetiou lva1|sing a vortiral motion and turlhor admixing action in the \Yllll'l' and an mixlure as it passes through lr 7i", 'lhev also serve to avoid \Vllill llilllullll' and imure the proper distribution ol the mixture of and air to the apertures of the bottom zinc; so that it will issue uniformly zip-l lh ill} practically equal fol-re llll'llllgllfllll 111 live series of apertures.

The apparatus employed in the pun-live of llll invention is illustrated in the zn'runv panyino drawing \vlu-reiu;

Referring to the drmvino (L imlimrs a 105 bath tub, which in bu pi-mjiil-wl with Jha usual \'r!llu\\ d and ill lihrv The ably oi oval form upon iln: p ll-om of U5 in Figs. 1 and 2; or, if provided with a central pipe 1), it may be set within countersunk recesses of a wooden bottom 14., as shown in Figs. 4 and 5. The bottom ring is provided with a series of apertures, as shown, the apertures on the inner sides of the ring being directed downwardly and inwardly and the apertures on the upper side of the ring being directed upwardly and being of slightly larger size than the lower apertures. The bottom ring connects by an elbow c with a down-take d, which may be integral therewith. At the upper part of the upright d is arranged the housing e, which is provided with a side branch r having a cutoff cook or valve f. The pipe g is intended to admit air into the housing 0,, under the injecting influence of the injector jet which communicates with the cold water supply pipe Z.

It will be found suitable to make the openings that are in that half of the oval pipe which is adjacent to the down-take d and elbow c of about 5- mm. bore and to make the openings in the other half of the oval pipe from 1 mm. to 1.} mm. bore. It is also recommended to space the openings about 1 cm. to 1% cm. apart for the best effects.

The pressure of the water injecting jet will conveniently be about three atmospheres but: may exceed that amount if desired.

In order -to temper'the mixture of cold water and air on its way to the bottom ring, a supply pipe'w is provided for the admission of warm water. The entrance of this warm water supply further assists in efle cting the intimate admixture of the air with the water column on its way to the bath tub,

and this intimate admixture is further insured by the extensions m, which have small openings at their outer ends and which are arranged respectively at opposite extremities of the oval bottonrring, the water and air mixture finding free eutrzmce into these extensions and being subjected therein to a vertical action and further mixing effect.

Having thus described my invention, what I claim is: I

1. Apparatus for producing bead-like aerations in baths, consisting of a bath tub, a perforated pipe lying in the bottom of the bath tub, a water supply pipe communicating with the bottom pipe, a water jet injector leading into the water supply pipe, a warm water pipe leading into the said water supply pipe, and an air pipe through which air is drawn by the water et injector into the water supply pipe; substantially as described.

2. Apparatus for producing bead-like aerat-ions in baths, consisting of a bath tub, a perforated pipe lying in the bottom of the bath tub, a water supply pipe communicating with the bottom pipe, a water jet injcc tor leading into the water supply pipe and an air pipe through which air is drawn by the water jet injector into the water supply pipe, the perforated pipe being of oval orm and being provided at opposite points with sack'like extensions; substantially as described. I

In testimony whereof I atlix my signature, in presence of two witnesses.
